Abstract

Means for connection (10) between a rod (12) and crosshead in a reciprocating compressor comprise threaded units, an anti-rotational securing device (49) and axial positioning elements, wherein the threaded units consist of a first inner lock nut (37), provided with an inner thread (39) onto which there is screwed a threaded end portion (24) of the rod (12) and provided with two outer threads (41, 42) with a different diameter, one of which is for connection to the left-handed anti-rotational securing device, and the units also consist of a second outer lock nut (38) in the inner diameter of which a thread (45) is provided.
